I am unable to place an internation PSTN call through the gateway whereas local and national call works fine. Call is rejected by the PSTN.
Is there any timer issue ?
IOS version is 12.2(4.2) with CCM 3.1(2c)

voice class codec 1
codec preference 1 g711alaw

Any idea ?

I tried 12.2.1 and 12.2.1c without success.
I didn't found 12.2.5a on the CCO, can you tell me where to find it ?
I see in your debug:
Called Party Number i = 0x80, '0033'
Is 0033 a complete number? I would expect that it's not. Can you try to remove the isdn sending-complete command, because you are sending 0033 and the telco is not going to wait for any more digits because you are sending the Sending Complete IE in the SETUP message.
Also, what is the route pattern that you have configured in CallManager, both for local/national calls as well as for the international calls?
No 0033 is not the complete number, I just hide the 7 last numbers. 00 is for international calls in France and 33 is the international France code. I must have tell you this, sorry.
national route pattern : 0.XXXXXXXXXX
international route pattern : 0.00!
this to avoid inter digit timeout for national calls.
Now I am a little confused. Are you saying that in the debug isdn q931 that the entire number was actually sent, not just 0033, and you deleted the number out when you posted your debug?
Yes, that's it, I put an explanation that was stripped because confusing with an HTML tag...
In the debug, the entire and correct number is sent
I already had a problem like this : I was able to call people connect with ISDN to the PSTN but not home user who used an analog connection. It was an IOS bug in v12.2.3 (timer pb). With 12.2.4 this feature works but still not international calls, even with a csim start command !
We had some weird problems on a PRI (call to cell-phone ended up in singapore), this solved the problem (on the serial int);
isdn map address . plan unknown type unknown
You can try this on your BRI (if you can do this on a BRI, I am not sure)
You never now...... :-)
We did have this same problem and it ended up being a timer issue. The problem happened more frequently on international calls to cell phones because they take longer to connect. The two items that corrected the problem for us were:
1. On your gateway, set the call type to unknown in stead of call manager.
2. In your router, on the interface for your PRI line (ex. 2/0:23) add the entry "ISDN T310 50000"
Yep the last guy to post, I think had the right idea. Below is what I did to fix a similar problem.
*configure the T310 timer in the CallManager Service Parameters to 60s
(it is prob configured to 10s)
*configure the T310 timer on the Gateway as described in the following
